[PATCH] thermal: rockchip: improve the warning log

[Shawn Lin <shawn.lin-TNX95d0MmH7DzftRWevZcw@public.gmane.org>]

There is no necessary to print warning agian and
again if we don't add rockchip,grf for dt, otherwise
I saw the following log when doning suspend-2-resume.
We only need to print it once when parsing dt. It looks
quite trivial but the log is apparently verbose.

[   26.615415] PM: early resume of devices complete after 1.539 msecs
[   26.622002] rk_tsadcv2_initialize: Missing rockchip,grf property
[   26.629359] rk_gmac-dwmac ff290000.ethernet: init for RGMII
[   26.639794] PM: resume of devices complete after 18.109 msecs
[   26.646925] Restarting tasks ... done.
